Tire tread design



FIG. 1 is a perspective view of a tire tread, showing my new design;

FIG. 2 is a front view thereof;

FIG. 3 is a right side view thereof;

FIG. 4 is a perspective view of a section of the tire tread as defined by lines a-a and b-b;

FIG. 5 is an enlarged view of the section of the tire tread defined by lines a-a and b-b in FIG. 4;

FIG. 6 is a front view of a section of the tire tread as defined by lines c-c and d-d:

FIG. 7 is an enlarged view of the section of the tire tread defined by lines c-c and d-d in FIG. 6;

FIG. 8 is a right side view of a section of the tire tread as defined by line e and line f; and,

FIG. 9 is an enlarged view of the section of the tire tread defined by line e and line f in FIG. 8.

The evenly-spaced broken lines shown in the drawings are for the purpose of showing environmental structure only, and form no part of the claimed design. The unevenly-spaced broken lines in the drawings are used to show the boundaries of FIGS. 5, 7, and 9, and form no part of the claimed design. 

I claim the ornamental design for a tire tread design, as shown and described.
